Python uses the requests module to complete get/post/proxy/custom header/custom Cookies

I. BACKGROUND notes

Because Python3 's urllib and Python2 have a lot of differences, and some of the urllib.request request is not quite in line with people's thinking habits (documents are quite ugly)

So I really don't want to use Python until I look at the Urllib.request document and notice the words below

Compared to requests is really good, the document is also clear; you need to install it yourself, but it is still more recommended.

1.1 Applicable version

For python2.6, python2.7, python3.4 and above, see the official note.

I'm using the latest python3.7.

1.2 Installing the Requests module

PIP Install pipenvpipenv Install requests

Second, use requests module to complete various operations 2.1 reference requests module

Import Requests

2.2 GET Request

Import requestsurl='https://www.baidu.com'= requests.get (URL) Print (R.status_code)

2.3 Post Request

Import requestsurl='https://www.baidu.com'data_post='just Put your data and use original format'= requests.post (url,data=data_post)Print (R.status_code)

2.4 Using proxies

HTTP proxy no problem, HTTPS seems a bit of a problem need to test again

ImportRequestsurl='http://docs.python-requests.org/en/master/'proxies={    'http':'127.0.0.1:8080',    'HTTPS':'127.0.0.1:8080'}r= Requests.get (url,proxies=proxies)Print(R.status_code)

2.5 Customizing headers

ImportRequestsurl='http://docs.python-requests.org/en/master/'Headers={    'user-agent':'self-defind-user-agent',    ' COokie':'name=self-define-cookies-in Header'}r= Requests.get (url,headers=headers)Print(R.status_code)

2.6 Custom Cookies

The experiment found that cookies that are set here do not take effect if cookies are defined in the custom header

Import requests

Url= ' http://docs.python-requests.org/en/master/'
cookies={' name1 ': ' Cookie1 ', ' name2 ': ' Cookies2 '}
#cookies =dict (name1= ' cookie1 ', name2= ' cookies2 ')
R = Requests.get (url,cookies=cookies)
Print (R.status_code)
